Description
Technical field
The present invention relates to a kind of derail crash device, belong to train operating safety guard technology field.
Background technology
China Express Railway construction in recent years obtains develop rapidly.But derailment accident is a very important major issue in railway development process always.The reason such as problem due to too fast, the irrational railway safeguard procedures of the speed of a motor vehicle, harsh climate condition and train self causes various countries the train was derailed that accident is of common occurrence, may cause mass casualties and property loss.Particularly for high ferro vehicle, because the speed of service is very fast, once derailing occur and collides with Adjacent Buildings, then more serious secondary disaster can be caused.Typical example is 2005, and Japanese JR good fortune is known that mountain line one arranges and sailed for by Bao Zhong the rapid learned and grind, and bend does not slow down, and causes the first five joint compartment to overstep the limit suddenly.After train and a car bump against, pour a domestic block.Casualties is heavy, and cause 107 people dead altogether, 562 people are injured.Therefore, the derailing train crash device of research and development high efficient and reliable, the safe operation for high-speed railway has extremely important realistic meaning.
The most easily suffering that derailing train clashes into, is also that to clash into the building that the most serious class of consequence closes on railroad track be exactly all kinds of train station structures.Modern New train station structure is generally greatly across elevated structure, and bottom is rail layer, and bullet train passes (i.e. main track) or parking (namely arriving hair line) of arriving at a station at a high speed at this.Owing to being subject to the restriction of each side factor, the distance between the structure of high ferro station and train is very limited, and often less than 1m, this proposes severe challenge to research and development reliable derailing efficiently train crash device.Meanwhile, the cost of Novel high-speed train is also very high and also may have a large amount of passengers inside derailing train, while avoiding clashing into and causing station structure generation heavy damage, also should alleviate the damage to derailing train as far as possible.
Summary of the invention
The object of this invention is to provide a kind of derail crash device based on multiple defence line, clash into while causing station structure generation heavy damage avoiding derail, alleviate derailing train and the train internal staff injury that may cause to the full extent, guarantee station structure and internal staff's safety.
Technical scheme of the present invention is as follows:
Based on a derail crash device for multiple defence line, it is characterized in that: this device comprises four lines of defense: the first defence line is check rail, secondary defense is porotective wall, and the 3rd defence line is energy-absorbing block, and the 4th defence line is protection cuff; Described protective jacket cuff is located at outside station column; Described energy-absorbing block is arranged on protection cuff, and be positioned at the same side with track, this energy-absorbing block is made up of proliferation part and energy absorbing component two parts; Described porotective wall, between station column and track, is the concrete structure of arc inside adopting; Inner side and the track foundation of this concrete structure are connected as a single entity.
In technique scheme, described energy-absorbing dog height is 1.5 ~ 2.5m, and center is 1.5 ~ 2m apart from track cross level face height; Described proliferation part adopts steel plate or steel flap; More energy absorbing component is arranged by the thin-walled square steel pipe filling out reticulated foams aluminium in arranging to form.
Protection cuff of the present invention is formed by the Plate Welding that 20 ~ 40mm is thick, distance from top track cross level face 2-3m.Described porotective wall height is 40 ~ 60cm.
The present invention has the following advantages and high-lighting effect: this device can arrange four lines of defense, the first line of defence in less space: check rail; Second defence line: porotective wall; Three lines of defence: energy-absorbing block; Four lines of defense: protection cuff; Four lines of defense forms an organic whole, not only at utmost can alleviate the destruction that train may be subject to, and the injury that train internal staff may cause can be alleviated to the full extent, and it is little to take up room, can be arranged on very easily on all kinds of newly-built and existing high ferro station, there is good practicality and feasibility.

Detailed description of the invention
Below in conjunction with accompanying drawing to principle of the present invention, structure and and concrete enforcement be described further:
This protector is made up of four lines of defense altogether, the first line of defence: check rail; Second defence line: porotective wall; Three lines of defence: energy-absorbing block; Four lines of defense: protection cuff.
The first line of defence: in the middle of the track 3 in house post 10 side of pulling in, traditional check rail 4 is set, for low speed to sending out station train (below 40km/h), if after train surprisingly derails, its single wheel is blocked by check rail 4, opposite side wheel is positioned on sleeper 2, and car body slightly tilts to cylinder, and train is in guiding downslide departures house post 10 scope of check rail 4, unlikelyly to collide, and substantially can not cause damage to train.
Second defence line: 3 arrange porotective wall 5 between station column 10 and track, porotective wall 5 is high 40 ~ 60cm, and inner side is the concrete structure of arc, and inner side and the track foundation 1 of this concrete structure are connected as a single entity.For medium speed's train by (40 ~ 80km/h), when check rail 4 cannot stop derailing train, porotective wall 5 can make its single wheel of derailing train be positioned on sleeper 2, opposite side wheel is positioned on porotective wall 5, car body is to rolling tiltedly away from station column 10, train is by guiding downslide departures house post 10 scope at porotective wall 5, and now train only can occur very limited damage at the position such as wheel and support, at utmost alleviates the destruction that train may be subject to.
Three lines of defence: be arranged on protection cuff 9, being positioned at the energy-absorbing block 6 of the same side with track 3, is highly 1.5 ~ 2.5m, and center is 1.5 ~ 2m apart from track 3 elevation of water, is made up of proliferation part 7 and energy absorbing component 8.Proliferation part 7 for by derailing train to the shock disperses force of station column 10, be made up of steel plate or steel flap, the thickness of steel plate is generally about 20mm.Energy absorbing component 8 for by the impact after dispersion and kinetic energy dissipation, combined by the thin-walled square steel pipe filling out reticulated foams aluminium in arranging, the wall thickness of thin-wall steel tube is generally about 2mm, internal diameter 10cm, length 20cm, foam density 300 ~ 500kg/m more
3, for passing through train (80 ~ 160km/h) at a high speed, porotective wall 5 can retrain the outside translation of derailing train, but train rolling may occur and bumps against with station column 10.Now; energy-absorbing block 6 can stop the outside tumbling motion of train; and its kinetic energy that dissipates; thus can available protecting station column 10; and consume energy due to the distortion of energy-absorbing block 6; can avoid derailing train, in knockout process, gross distortion occurs, thus the safety of the inner passenger of available protecting train.
Four lines of defense: station column 10 arranged outside protection cuff 9, protection cuff is welded into by 20 ~ 40mm steel plate, be set in outside station column 10, distance from top track 3 horizontal plane 2 ~ 3m, protection cuff effectively can increase station column 10 impact resistant capability, the main track of 160km/h is greater than by train for Negotiation speed, once there is derailment accident and front three lines of defence when all losing efficacy, train by inevitably and station column 10 there is hard collision.Now protect cuff and can play triple protective action: local impact's power of 1. disperseing bullet train; 2. flexural strength and the bending rigidity of column is improved; 3. retrain column concrete, improve concrete strength and ductility.Thus can effectively avoid station column meet with shock and lost efficacy, guarantee station structure and internal staff's safety.
